Ajax跨域请求中的Cookie问题(默认不带cookie等凭证)

时间:2021-10-31 14:58:21

1.原生Ajax请求方式,设置跨域请求附带详细参数

var xhr = new XMLHttpRequest();
xhr.open("POST", "http://xxxx.com/demo/b/index.php", true);
xhr.withCredentials = true; //支持跨域发送cookies
xhr.send();

2.Jquery的Ajax请求,设置跨域附带详细参数

$.ajax({
url: apiUrl.getCookie('getone'),
data: { age: 11 },
xhrFields: {
withCredentials:true //支持附带详细信息
},
crossDomain:true,//请求偏向外域
success: function (data) {
alert(data);
}
});

3.服务端支持

header("Access-Control-Allow-Credentials: true");
header("Access-Control-Allow-Origin: http://www.xxx.com");

或者webconfig中修改配置:

  <configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="http://www.xxx.com" />
<add name="Access-Control-Allow-Methods" value="GET, POST" />
</customHeaders>
</httpProtocol>
</system.webServer>
</configuration>

能够成功使用带有 Cookie 的资源请求需要满足以下几个条件

  • XMLHttpRequest 对象中指定了 withCredentials = true

  • 服务器响应头中 Access-Control-Allow-Credentials: true

  • 服务器响应头中 Access-Control-Allow-Origin 不能为 *
